Ibikoresho byo kugurisha kuri Laser Diode Utubari: Ikiraro Cyingenzi Hagati yimikorere no kwizerwa

Mugushushanya no gukora inganda zifite ingufu nyinshi za semiconductor laseri, utubari twa laser diode nkibice byingenzi bitanga urumuri. Imikorere yabo ntabwo ishingiye gusa kumiterere yimbere ya chip ya laser ahubwo binaterwa cyane nuburyo bwo gupakira. Mubice bitandukanye bigira uruhare mubipfunyika, ibikoresho byo kugurisha bigira uruhare runini nkumuriro wumuriro n amashanyarazi hagati ya chip na sink.

1. Uruhare rwabacuruzi muri Laser Diode Bars

Utubari twa Laser diode mubisanzwe duhuza ibyuka byinshi, bikavamo ingufu nyinshi hamwe nibisabwa bikomeye byo gucunga ubushyuhe. Kugirango ugabanye ubushyuhe bwiza kandi butajegajega, ibikoresho byagurishijwe bigomba kuba byujuje ibi bikurikira:

Conduct Umuyoboro mwinshi w'amashanyarazi:

Iremeza kohereza ubushyuhe neza muri chip ya laser.

Et Ubushuhe bwiza:

Itanga guhuza gukomeye hagati ya chip na substrate.

Point Ingingo ikwiye yo gushonga:

Irinda guhinduka cyangwa gutesha agaciro mugihe cyo gutunganya cyangwa gukora.

Co Coefficient ihuye yo kwagura ubushyuhe (CTE):

Kugabanya imihangayiko yumuriro kuri chip.

Resistance Kurwanya umunaniro mwiza:

Kongera ubuzima bwa serivisi igikoresho.

2. Ubwoko busanzwe bwa Solder yo gupakira Laser Bar

Ibikurikira nubwoko butatu bwibikoresho byagurishijwe bikunze gukoreshwa mugupakira utubari twa laser diode:

①Zahabu-Tin Alloy (AuSn)

Ibyiza:

Eutectic igizwe na 80Au / 20Sn hamwe no gushonga ya 280 ° C; amashanyarazi menshi hamwe nimbaraga za mashini.

Ibyiza:

Ubwiza buhebuje bwo hejuru, ubushyuhe burebure bwumuriro, butarangwamo umwanda, kwizerwa cyane

Porogaramu:

Sisitemu ya gisirikari, ikirere, hamwe na sisitemu yo mu rwego rwo hejuru.

②Indium Yera (Muri)

Ibyiza:

Ingingo yo gushonga ya 157 ° C; byoroshye kandi byoroshye.

Ibyiza:

Imikorere yo gusiganwa ku maguru meza cyane, guhangayikishwa cyane na chip, nibyiza kurinda inyubako zoroshye, zikwiranye nubushyuhe buke bwo guhuza

Imipaka:

Gukunda okiside; bisaba ikirere cya inert mugihe cyo gutunganya, imbaraga za mashini zo hasi; ntabwo ari byiza kubintu byinshi biremereye

③Sisitemu yo kugurisha sisitemu (urugero, AuSn + Muri)

Imiterere:

Mubisanzwe, AuSn ikoreshwa munsi ya chip kugirango ifatanye neza, mugihe In ikoreshwa hejuru kugirango izamure neza.

Ibyiza:

Ihuza kwizerwa cyane hamwe no kugabanya ibibazo, itezimbere muri rusange gupakira, guhuza neza nibikorwa bitandukanye

3. Ingaruka zubuziranenge bwibicuruzwa kumikorere yibikoresho

Guhitamo ibikoresho byo kugurisha no kugenzura bigira ingaruka cyane kumikorere ya electro-optique hamwe nigihe kirekire cyibikoresho bya laser:

Munsi yimbaraga zikomeye zikomeza, niyo nenge ntoya mugurisha irashobora gutuma habaho ubushyuhe bwumuriro, bikaviramo kwangirika kwimikorere cyangwa ibikoresho byananiranye. Kubwibyo, guhitamo ibicuruzwa byujuje ubuziranenge no gushyira mubikorwa uburyo bwo kugurisha neza nibyingenzi kugirango ugere kumurongo wizewe cyane.

4. Ibizaza hamwe niterambere

Mugihe tekinoroji ya laser ikomeje kwinjira mubikorwa byo gutunganya inganda, kubaga ubuvuzi, LiDAR, nizindi nzego, ibikoresho byo kugurisha ibikoresho byo gupakira lazeri bigenda byiyongera muburyo bukurikira:

①Kugurisha ubushyuhe buke:

Kugirango uhuze hamwe nibikoresho byoroshye

②Ugurisha ku buntu:

Kuzuza RoHS nandi mabwiriza y’ibidukikije

③Ibikoresho byo hejuru cyane yubushyuhe (TIM):

Kugirango urusheho kugabanya ubushyuhe bwumuriro

④Tekinoroji yo kugurisha mikoro:

Gushyigikira miniaturizasiya no kwishyira hamwe kwinshi

5. Umwanzuro

Nubwo ari nto mubunini, ibikoresho byo kugurisha nibyo bihuza byingenzi byemeza imikorere nubwizerwe bwibikoresho bikomeye bya laser. Mu gupakira utubari twa laser diode, guhitamo uwagurishije neza no guhitamo inzira yo guhuza nibyingenzi kugirango ugere kubikorwa byigihe kirekire.

6. Ibyerekeye Twebwe

Lumispot yiyemeje guha abakiriya ibikoresho byumwuga kandi byizewe bya laser hamwe nibisubizo byo gupakira. Hamwe n'uburambe bunini muguhitamo ibikoresho, kugurisha imicungire yubushyuhe, no gusuzuma kwizerwa, twizera ko kunonosorwa muburyo burambuye bitanga inzira yo kuba indashyikirwa. Kubindi bisobanuro kubijyanye na tekinoroji yo gupakira laser, wumve neza.
